In the realms of design, engineering, and typography, precision and accuracy are paramount. Understanding the conversion between points (pt) and millimeters (mm) is essential for ensuring consistency and accuracy in measurements. This comprehensive guide will delve into the intricacies of this conversion, providing valuable information, tips, and insights.
To convert points to millimeters, multiply the point value by 0.35278 (1 pt = 0.35278 mm).
Formula:
mm = pt × 0.35278
To convert millimeters to points, divide the millimeter value by 0.35278 (1 mm = 2.83465 pt).
Formula:
pt = mm / 0.35278
For quick reference, here are some useful conversion tables:
